6 Open-Source Tools for Web Crawling and Scraping in 2026

6 open-source GitHub repositories for crawling and scraping the web 1./ Firecrawl An open-source web-data API, also available as a hosted service, for searching, scraping, mapping and crawling the web. It can convert individual pages into Markdown, HTML, screenshots or structured JSON, discover URLs across a website, crawl multiple pages and process large URL batches asynchronously. It also supports interacting with pages through actions such as clicking, scrolling and typing before extracting the content. 2./ Crawl4AI A Python crawler and scraper built around producing content for LLMs, RAG pipelines and AI agents. It generates clean or filtered Markdown, supports structured extraction using CSS, XPath or LLMs, and can run deep crawls using strategies such as breadth-first search. Its Playwright-based browser layer can execute JavaScript, preserve sessions, use proxies and handle dynamic or infinite-scroll pages. 3./ Scrapling An adaptive Python scraping framework that supports everything from fetching a single page to running concurrent, multi-session crawls. Its adaptive selector system can save an element’s properties and search for the most similar element when the original selector stops matching after a page redesign. Its spider framework also includes streaming, concurrency controls, pause and resume, and proxy rotation. 4./ Crawlee A JavaScript and TypeScript library for building web crawlers, scrapers and browser-automation workflows. It works with lightweight HTTP and HTML parsing as well as Playwright and Puppeteer for JavaScript-rendered pages. Crawlee provides persistent URL queues, structured-data storage, automatic concurrency scaling, session management and proxy rotation, while leaving the page-specific extraction logic to the developer. 5./ Scrapy A high-level Python framework for crawling websites and extracting structured data. Developers create spiders that issue requests, follow links and parse responses using CSS or XPath selectors. Scrapy’s engine coordinates scheduling and downloading, while item pipelines can validate, transform or store extracted records, and feed exports can write results to formats such as JSON, CSV and XML. 6./ Maxun An open-source, no-code web-data platform that combines extraction, scraping, crawling and web search. Its Recorder Mode captures browser actions and turns them into reusable extraction robots, while its AI Mode uses natural-language instructions for structured extraction. It can also convert webpages into Markdown or HTML, capture screenshots, crawl websites with configurable scope and run locally through self-hosting. ---- "The web is the largest database in the world."

I checked each of the six tools against their GitHub repos and documentation.

All six descriptions are accurate:

1. Firecrawl — it offers search, scrape, interact, crawl, and map endpoints, converting URLs to markdown, HTML, screenshots, or structured JSON, plus actions like click, scroll, write, and wait before extraction, and it's available both as a hosted API and self-hostable open-source project. Matches the post precisely. GitHubGitHub
2. Crawl4AI — it's an open-source, async Python crawler built on Playwright that turns pages into clean, LLM-ready Markdown or structured JSON for RAG pipelines, with deep crawling via BFS/DFS/BestFirst strategies and support for CSS, XPath, and LLM-based extraction. Accurate. ScrapingBee + 2
3. Scrapling — it features smart selection via CSS/XPath/text/regex, automatically finds elements similar to previously found ones, and includes a full spider framework alongside a familiar Scrapy/BeautifulSoup-like API, and its adaptive matching compares a stored fingerprint against the new DOM tree and returns the highest-confidence match when a selector breaks after a site redesign. Matches the post's "adaptive selector system" description well. GitHubUse Apify
4. Crawlee — it's a Node.js/TypeScript library working with Puppeteer, Playwright, Cheerio, and JSDOM, offering a persistent URL queue, automatic scaling, integrated proxy rotation, and session management. Confirmed accurate. GitHub
5. Scrapy — this is a long-established, well-documented Python framework; the post's description (spiders, CSS/XPath parsing, item pipelines, JSON/CSV/XML exports) matches its standard, well-known architecture.
6. Maxun — its Recorder Mode records browser actions into a reusable extraction robot, its AI Mode uses natural-language instructions for LLM-powered extraction, and it can convert pages to Markdown/HTML, capture screenshots, and crawl full sites, with self-hosting available as an alternative to the hosted version. Matches precisely — this post's Maxun description appears to be drawn almost verbatim from the project's own README. GitHubGitHub

One minor nuance worth flagging: Maxun is licensed under AGPLv3, a copyleft license — commercial use of the as-is tool is fine, but modifying and redeploying it as a service requires disclosing source code, similar to Firecrawl's licensing. The post doesn't mention licensing for any of the six tools, which isn't inaccurate, just an omission worth knowing before building a commercial product on any of them. Dev

No fabricated features, no incorrect tech-stack claims, no wrong licensing framed as permissive when it isn't. This is an accurate, well-researched roundup.
